particular portion 2, and an outline inapis shown thereon at 3,

which map, it will be understood, may contain a. graphical representation of any or all the topographical features, etc., of the regionin question. This base map is secured r hinged as at 4:, at its outer edge to one member, 5, of a cover or back Within which each of the maps of the-set isintended tobe inclosed, and the inner edge of the sheet 2 is free te swing about the hinge member 4 to permit Sheets carried by the other m'ernber, 6, of the cover to be brought' into position to cooperate, one at a time, With'the base sheet 0. Here, for simpliclty, but Vthree sheets are shown as secured to the cover member 6, these being attached near theirv inner enges by any suitable means, such als l0, to the cover at a point near the hinge, 11, thereof. Said three sheets are designated by 7, S and 9 respectively. Each is approxif mately the'saine size as the base'sheet 2 and each has an outline map thereon. like that shown at 3 hated in Figs. Ll, 6 and 8 respectively by 3*, 3b

in question will uestion have beenv u a showing of all the which it is desired t0` and this outline map'isdesig:

and 3.. The outline is so placed on each y0fthe sheets "l", 8 and 9 that when these sheets are turned over on to the sheet 2 the outlines 3, 3b and 3c respectively will register with the outline 3. Q

The material of the base sheet Q'rnayfof ourse, he any suitable for the purpose and will usually he relatively opaque, but 'the .heets 7, 8 and 9 should be of transparent iateriah such as tracing paper, linen, celluloid, etc., in order that the topographical and other features of the hase inap 3 may show -elearly through each superimposed sheet,

8 or 9. lllhile the sheets 7, 8. and 9are all s0 printed that their :respective map outlines register with one another, and are all hin ed rey' may he swung from, their to the cover near their inner edges so t at over on to the base map, the other indications on the maps of the sheets 7, 8 and 9 differ from one another and, of course, also from the indications contained within the outlineI of the map on the base sheet 2. Thus the outline 3" contains within it, as indicated in Fig. fi, indications of the political divisions oilI the Spanish peninsula, during the Aninth century A.. D., these diierent indications clearly illustrating graphically the political subdivisions of the territory of the peninsula during said period. In Fig. 6 the political subdivisions indicated are diderent from those shown in Fig. 4c and represent the political conditions existing so far as territorial subdivision and nomenclature are concerned during the twelfth century A. D. In a similar manner Fig. 8 illustrates corresponding subdivisions, etc., for the present time,

It will of course be obvious that the history of the particular portion of the earths surface illustrated in these drawings may be graphically represented, in a manner similar to that indicated, for each and every century, from the beginning of the history of the region in question, or for any other peri- .ods desired; and it will also be clear that large numbers of other kinds and grades of historical information may be shown on such maps, and the history, in connection with the geography, oi any particular portion of the earths surface quickly indicated from the earliest times down to the present time, the object being so to associate the history of the development of any particular country or region with the geography thereof that both the history and the geography of such region for any particular period will appear at a glance.

An important feature of such a set of maps as this is that each map indicating a particular period of the history of the region in question should not only be combined with a base map or sheet in such a manner as to be readily associated with it, as by superimposition, for educational purposes, but should also be so combined with the base sheet that it may be quickly gotten out of the way and another sheet representing another periodbrought into posi tion to register with the hase map. The manner in which.

this is done in the present case will be clear by referring to the figures consecutively, from which it will be seen that sheets 7, 8 and 9 are brought one at a time over upon the base map and are then swung under said base map one at a time when a map of a new period is to be brought into position for use. The hinge member 4f, in addition to constituting a hinge for the attachment of the sheet 2, also serves, as will be evident by reference to Figs. 5 and 7, as a means for spacing the sheets properly when a considerable number of sheets have to be used in connection with the base sheet and foldedr under it as indicated in Fig. 7.

lVhat I claim is:

1. In an article of the class described, the combination with a hinged cover, of ay pair of map sheets one being' a relatively opaque base sheet secured at its outer edge to an' outer edge ofthe cover and the other being,

a transparent sheet hinged at its inner edge near the hinge of the cover and containing a map of like outline to said base map and having within said out-line indications diiierine from those of said base map, said transparent map being adapted to be swung over on to the base sheet to bring its map outline into registration with that of said base map and also adapted to be swung under said base map and covered thereby. l

2. -ln an article of the class described, the combination with a hinged cover, of a pair of map sheets one being arelatively opaque base sheet hinged at its/"outer edge t an outer edge of the cover'` for swinging movement, and the other being a transparent sheet hinged at itsinner edge near the liinge of the cover and containing a Amap of like outline to said base map and having within said outline indications differing from those of said hase map, said transparent map being adapted to be swungiover on to the base sheet 'to bring its map outline into registrationwith that of said base map and also adapted to be swung,` under said base map and covered thereby.

3. In an article of the class described, the combination with a hinged cover, of a relatively opaque base sheet secured at its outer edge to an outer edge of the cover and containing a base map, and a plurality of transparent sheets hinged at their inner edges near the hinge of the cover and each con' taining a map of like outline to said base map but having within said outline indications diil'ering .from those of every other map, each of said transparent maps being adapted to be swung over on to the base sheet to bring its map outline into registration with that of said base map. 4.
